note 101534 added to function.isset

If you want isset() to be true even if variable has been set to NULL, use @is_null() along with isset(). <?php $foo=null; return isset($foo) ? true : false ; // returns false return isset($foo) || @is_null($foo) ? true : false ; // returns true ?> ---- Server IP: 69.147.83.197 Probable Submitter: 95.61.51.75 ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- https://master.php.net/note/edit/101534 Del: integrated -- https://master.php.net/note/delete/101534/integrated Del: useless -- https://master.php.net/note/delete/101534/useless Del: bad code -- https://master.php.net/note/delete/101534/bad+code Del: spam -- https://master.php.net/note/delete/101534/spam Del: non-english -- https://master.php.net/note/delete/101534/non-english Del: in docs -- https://master.php.net/note/delete/101534/in+docs Del: other reasons-- https://master.php.net/note/delete/101534 Reject -- https://master.php.net/note/reject/101534 Search -- https://master.php.net/manage/user-notes.php
